Stinky Situation

"My school has an open campus policy, which means that we're allowed to leave the school during free periods. I tend to walk home during lunch because I live close to school. One day I was walking through the hall after getting back from lunch, and everybody was staring at me and covering their noses. I was so confused until one of my friends told me to lift up my foot. Not only was there dog poop on my shoe, but I had made a long trail of it down the hall!"
